====================
dpaa2-switch: add support for LAG offload

This patch set adds support in dpaa2-switch for offloading upper bond
devices.

The first two patches remove the necessity to hold rtnl_lock during the
event processing workqueue by ensuring that all event were processed
before any changes in FDB layout happens.

Patch #3 updates the logic around choosing the FDB that should be used
on a switch port. This is necessary since with the addition of the LAG
offload, we need to take into account all ports which are under the same
bridge, even though not directly.

The next four patches clean up the FDB event by making them easier to
integrate with bond devices and also add the
dpaa2_switch_port_to_bridge_port() helper to be used in the LAG offload
support.

The 8th patch adds the necessary new APIs for the LAG configuration
while the next one uses them, both in the prechangeupper phase and the
changeupper one. Which ports can be part of the same LAG group is
configurable at boot time, thus we use the prechangeupper callback in
order to validate that a requested configuration can be offloaded or
not.

This set also extends the handling of FDBs and port objects so that they
are handled by the driver even on an offloaded bond device.
